FIELD OF THE INVENTION

This invention relates to the eradication of pathogens, and more particularly to a recharging and disinfecting docking station for portable electronic products.

BACKGROUND OF THE INVENTION

Medical environments, such as hospitals and doctors' offices, are known to contain a relatively high concentration of pathogens. As a result, it is desirable to reduce such pathogens wherever they exist in such environments. As a doctor makes his rounds from patient to patient in a hospital, for example, the objects the doctor carries are susceptible to contamination throughout the day.

One such object a doctor may routinely carry is a medical tablet computer, which a doctor may use to make notes on a patient file, write prescriptions, and the like. Such portable electronic devices frequently need to be recharged, yet currently there is no provision in recharging stations for such devices for disinfecting such devices.

Therefore, there is a need for a device that not only charges portable electronic devices, but that also concurrently disinfects such devices. Such a needed device would allow for the charging of multiple portable electronic devices, and would ensure disinfecting wavelengths of light reach substantially every surface of each portable electronic device therein. The present invention accomplishes these objectives.

SUMMARY OF THE INVENTION

The present device is a disinfecting docking station for at least one portable electronic device, such as a medical technician's tablet computer, that has at least one recharging connector. A substantially opaque enclosure is adapted to receive the at least one portable electronic device therein through at least one openable side. The enclosure further includes at least one door for selectively sealing the openable side. The enclosure may include reflective inner surfaces therein for reflecting disinfecting wavelengths of light.

A recharging means for recharging each of the at least one portable electronic device through the recharging connector thereof is adapted to transmit disinfecting wavelengths of light to the at least one portable electronic device. The recharging means preferably includes a backplane connector for electrically communicating with the recharging connector of the at least one portable electronic device. The back plane connector is connected with a power source and is preferably at least partially transparent to the disinfecting wavelengths of light and capable of transmitting such light to substantially all of the surfaces of the recharging connector.

At least one means of supporting each of the at least one portable electronic device is included, each means of supporting adapted to transmit the disinfecting wavelengths of light to the at least one portable electronic device. Preferably each means of supporting each include at least one shelf surface, each of which is substantially transparent to the disinfecting wavelengths of light. Each shelf surface may be comprised of a relatively small surface area where actually contacting the portable electronic device.

At least one disinfecting means, each adapted for producing the disinfecting wavelengths of light only when the door is in a closed position, is included. A control circuit may be further included and electrically connected with the power source, a user interface disposed on an outside surface of the enclosure, a switch for detecting when the door is in the closed position, and the ultraviolet light source. Such a control circuit includes a timer for activating the ultraviolet light source only when the switch indicates that the door is in the closed position and only for a predetermined period of time once activated by the user interface.

In use, with at least one of the portable electronic devices supported by the means of supporting within the enclosure and the door in the closed position, the means for disinfecting may be activated to produce the disinfecting wavelengths of light, illuminating substantially each surface of each of the portable electronic devices for a predetermined period of time.

The present invention is a device that charges and concurrently disinfects portable electronic devices. The present device allows for the charging of multiple portable electronic devices, and ensures disinfecting wavelengths of light reach substantially every surface of each portable electronic device therein. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

Additionally, the words “herein,” “above,” “below” and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word “or” in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list.

FIGS. 1 and 2 illustrate a disinfecting docking station 10 for at least one portable electronic device 20, such as a medical technician's tablet computer, that has at least one recharging connector 22 and may include various crevices 26 therein for air ducting ports, alternate connectors, door or compartment actuators, or the like. While the illustrations herein show the invention as used with tablet computers, any portable electronic device may be used, such as portable phones, music players, electronic book readers, or other electronic devices used in environments where reduction of pathogens is desirable.

A substantially opaque enclosure 30 is adapted to receive the at least one portable electronic device 20 therein through at least one openable side 35. The enclosure 30 further includes at least one door 40 for selectively sealing the openable side 35 between a closed position 41 and an open position 42 (FIG. 1). The door 40 is preferably connected with the enclosure 30 through a suitable hinge arrangement. The enclosure 30 may include reflective inner surfaces 90 therein for reflecting disinfecting wavelengths of light 65 about the enclosure 30. The enclosure 30 is made of any suitably rigid, strong, opaque material, such as metal, plastic, or the like.

A recharging means 50 for recharging each of the at least one portable electronic device 20 through the recharging connector 22 thereof is adapted in one embodiment to transmit disinfecting wavelengths of light 65 to the at least one portable electronic device 20. The recharging means 50 preferably includes a backplane connector 52 for electrically communicating with the recharging connector 22 of the at least one portable electronic device. The back plane connector 52 is connected with a power source 80 and is preferably at least partially transparent to the disinfecting wavelengths of light 65 and capable of transmitting such light 65 to substantially all of the surfaces of the recharging connector 22. In one embodiment, the backplane connector 52 includes a plurality of elongated, relatively thin electrical pins 150 (FIG. 2), around which the disinfecting wavelengths of light 65 may travel so as to fully expose the recharging connector 22. The backplane connector 52 may be included at a rear side of the enclosure 30, as illustrated, or elsewhere within the enclosure 30 as necessary based on the type of portable electronic devices used therewith and the location of its recharging connector 22.

At least one means of supporting 70 each of the at least one portable electronic device 20 is included, each means of supporting 70 adapted to transmit the disinfecting wavelengths of light 65 to the at least one portable electronic device 20. Preferably each means of supporting 70 includes at least one shelf surface 72, each of which is substantially transparent to the disinfecting wavelengths of light 65. In one embodiment, each means of supporting 70 includes at least one reflective surface 90 for reflecting a portion of the disinfecting wavelengths of light 65 into a crevice 26 of one of the at least one portable electronic device 20, as determined by the particular portable electronic device 20 used with the docking station 10. Such a crevice 26 may be, for example, an inset connector, a stylus or pen cavity, an inset screw access aperture, or the like. Each shelf surface 72 may be comprised of a relatively small surface area where actually contacting the portable electronic device 20, and may include small prongs, rollers (not shown) or other means having a small contact area with the electronic device 20. As such, 99% or greater of the surface 25 of each portable electronic device 20 may be exposed to the disinfecting wavelengths of light 65.

Alternately, each means of supporting 70 may be opaque and include support pins (not shown) that alternately extend and retract, such that, where alternately supported, each portable electronic device 20 is exposed to the disinfecting wavelengths of light 65 in an alternating fashion.

At least one disinfecting means 60, each adapted for producing the disinfecting wavelengths of light 65 only when the door is in the closed position 42, is included. Preferably each disinfecting means 60 includes an ultraviolet light source 62, such as an ultraviolet light bulb. The enclosure 30 may further include a plurality of ultraviolet light filters 180 (FIG. 7) fixed within the enclosure 30 to block at least some of the ultraviolet light 65 from sensitive areas 29 of the portable electronic device 20, such as photocells or camera elements thereof, for example.

A control circuit 100 (FIGS. 1 & 3) may be further included and electrically connected with the power source 80, a user interface 110 disposed on an outside surface 38 of the enclosure 30, a switch 120 for detecting when the door 40 is in the closed position, and the ultraviolet light source 62. Such a control circuit 100 includes a timer 130 for activating the ultraviolet light source 62 only when the switch 120 indicates that the door 40 is in the closed position and only for a predetermined period of time once activated by the user interface 110. The user interface 110 and control circuit 100 may provide options for delivering varying durations or intensities of the disinfecting wavelengths of light 65, based on selections made at the user interface 110. For example, overnight disinfection of each portable electronic device 20 may include longer durations or stronger intensities of the disinfecting wavelengths of light 65 than disinfection between patient encounters. Further, the control circuit 100 may include provisions for illuminating a portion of the total number of ultraviolet light sources 62 within the enclosure 30, based on the number of portable electronic devices 20 contained therein.

In use, with at least one of the portable electronic devices 20 supported by the means of supporting 70 within the enclosure 30 and the door 40 in the closed position 41, the means for disinfecting 60 may be activated to produce the disinfecting wavelengths of light 65, illuminating substantially each surface 25 of each of the portable electronic devices for a predetermined period of time.

In one embodiment of the invention, each means for recharging 50 may be a retractable connector (not shown), such that after the predetermined period of time has elapsed and the means for disinfecting 60 has been deactivated by the control circuit 100, such a retractable connector may extend to engage the recharging connector 22 of the portable electronic device 20, the recharging connector 22 having been thoroughly disinfected by the disinfecting wavelengths of light 65 while previously disengaged from the means for recharging 50. In such an embodiment, the backplane connector 52 includes a motorized arrangement (not shown) for engaging the recharging connector 22, the motorized arrangement controlled by the control circuit 100. It is understood that the term “recharging connector” used herein may also refer to other types of connectors, such as network connectors, interface connectors, VGA connectors, and the like.

The control circuit 100 may allow for varying exposure time and intensity of the disinfecting wavelengths of light 65 depending on selections made at the user interface 110. For example, a “double” disinfecting dose of the disinfecting wavelengths of light 65 may be selected on the user interface 110, which may double the exposure time of each portable electronic device 20 to the disinfecting wavelengths of light 65, for example. Further, in the case where the enclosure 30 holds a plurality of the portable electronic devices 20, any particular device 20 may be selected for exposure to the disinfecting wavelengths of light 65 at the user interface 110. For example, “bay 3” (not shown) may be selected, whereupon the control circuit only activates the ultraviolet light sources 62 associated with that particular location within the enclosure 30. A suitable embodiment for such functionality is illustrated in FIG. 4.

In one embodiment, the control circuit 100 is further connected to at least one photocell 190 sensitive to ultraviolet light, such that the control circuit 100 may activate the ultraviolet light source 62 only for a duration sufficient to provide a predetermined dose, or number of lumens, for example, to each portable electronic device 20, as determined by the at least one photocell 190 and the control circuit 100 (FIG. 3).

In one embodiment, each door 40 includes the means of supporting 70 and is pivotally attached with the enclosure 30 at a lower end 43 thereof (FIGS. 8 and 9). In such an embodiment, the enclosure 30 may be adapted to hold only a single portable electronic device 20, or the enclosure 30 may be equipped with a plurality of such doors 40 to hold a plurality of single portable electronic devices 20.

Preferably the power source 80 of the enclosure 30 includes a daisy chain connector 170 fixed with the enclosure 30 such that a plurality of enclosures 30 can be stacked (FIGS. 1 and 6), each enclosure 30 connecting with the daisy chain connector 170 of its next adjacent enclosure 30. As such, a single power source 80 may be included and connected to each enclosure 30 in stack of such enclosures 30 through each enclosure's daisy chain connector 170. It is understood that the power source may be an A/C line voltage source, or a low-voltage D/C source.

In a similar manner, each enclosure 30 may further include a network switch means 200 for providing network connectivity to each of the portable electronic device 20 stored therein. A network daisy chain connector 171 may be included for electrically connecting each network switch means 200 of each enclosure 30 in a stack of such enclosures 30, whereby only one network connection is required for the stack of enclosures 30. For portable electronic devices 20 that include wireless network capability, such as through WiFi or the like, a radio frequency refractor (not shown) may be included within the enclosure 30 so as to allow such wireless radio signals to pass substantially unimpeded through the enclosure 30.

While a particular form of the invention has been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. For example, the particular shape of the enclosure 30, and the number of portable electronic devices 20 illustrated in the drawings, may be altered considerably as desired. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
